In every reality, there're dark corners and recesses where imagination reigns supreme: that's...

The Underworld!

The Underworld invites you to
battle dragons and demons… to rescue the oppressed, and conquer
tyrants. Come face your own fears on a M.U.D. that was established in
1988. There's an ever-expanding 15,000 rooms in 120 zones with over
3500 distinct mobs and 3800 distinct objects.

You can create your alter-ego from 8 classes (with multi-class
characters too) and 10 races. Explore individually or join one of the
many active clans. Work your character through 65 levels of mortal
play and possibly become a God to continue through another 10 levels.
Another choice is to become a "Player-killer!" Stalk and kill other
player-killers for an entirely different dimension to mudding (don't
worry - nonplayer-killers are safe).

The Underworld also offers features
to make your experience more enjoyable. These include:

Quests from the gods

Individualized trials and prizes

Chaos Nights (where everyone can
be a player-killer but return safely)

A Hospital to buy more hitpoints
or mana, increases in attributes, or freedom from hunger/thirst

An automated auction system to
sell your loot when you're not even on

Based on sillymud, the code is very stable and has been reworked for optimum performance
and enjoyment. Lag is non-existant, as The Underworld is running on a
dedicate AMD K7 1.4Ghz server with 1Gig of RAM which is directly connected to the fiber backbone of a network with over 250Mb/s of available Internet bandwidth.
